Colorado celebrates 4/20

DENVER (AP) — Denver police say they have issued 28 citations for public consumption of marijuana and arrested one person accused of attempting to distribute the drug so far this weekend as revelers celebrate the traditional pot holiday of April 20.

Public consumption of marijuana is still illegal in Colorado, the first state to legalize — and regulate — recreational marijuana.

Of the infractions police reported Sunday, 22, including the arrest, happened Saturday. The remaining citations were as of about 2 p.m. Sunday, hours before crowds plan to smoke pot at 4:20 p.m. MDT.

In Boulder, University of Colorado officials closed the campus to all but students, faculty and staff to ensure no 4/20 celebrations were held.

Denver is one of many cities across the country where 4/20 marijuana celebrations are planned Sunday.
